Dear Mr. President:
I was distressed to learn that a long dormant volcano has erupted in Costa Rica resulting in considerable loss of life, personal injury and material damage.
I am asking our Embassy to work with you on emergency relief measures. Please let us know how we can be of help.
Sincerely,
LYNDON B. JOHNSON
